Forecast models from regional meteorological services project a daytime high of 35–36°C for Jeddah on October 15, consistent with the market’s strong 86% implied probability on 36°C. Mid-October climatology shows average highs near 34–36°C as the region transitions from peak summer, with the Red Sea moderating humidity and extremes while westerly winds and partial cloud cover limit further warming. Recent hourly observations at King Abdulaziz International Airport have already reached 34–36°C, aligning with ensemble guidance and reducing the likelihood of 37°C or higher. Stable atmospheric conditions and minimal precipitation risk support the narrow distribution around these values ahead of final daily maximum readings.
